In order to explore the role of mitochondria in proliferation promotion and/or apoptosis induction of lanthanum, the mutual influences between La3+ and Ca2+ on mitochondrial permeability transition pore (PTP) opening were investigated with isolated mitochondria from rat liver. The experimental results revealed that La3+ influence the state of mitochondria in a concentration-dependent biphasic manner...
Vanadium compounds have been recognized for their hypoglycemic effects; however, potential short and long-term vanadium toxicity has slowed the acceptance for therapeutic use. In the present work, three batches of vanadium-enriched chickpea sprout (VCS) were prepared by incubating chickpea seeds in presence of 200, 100, and 50 μg/ml of sodium orthovanadate (SOV). The effects of oral administration...
Lanthanum ion (La3+) was generally regarded as calcium antagonist and was used as calcium channel blocker. However, its potential biological effects on cells were poorly understood. In the present work, it was found that La3+ could induce rapid extracellular signal-regulated kinase (ERK) phosphorylation in both HeLa cells and NIH 3T3 cells, but different mechanisms were involved. At a concentration...
